GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 292,459, dated January 22, 1884.

Application filc d June ll, 18F3.

tors, of which the following is a specification,

reference being had therein to the accompanying drawing.

My invention relates to an improvement in gas regulators; and it consists in the construction and arrangement of a valve that-is acted upon by a spring, and which serves to regulate the pressure of the gas, in combination with a suitable valve-seat having vents through which the moisture that may collect in the pipe above the seat will be discharged,

and with a bar or plate having openings through whichthe gas can pass, this device being adapted to be secured to the meter between it and the service-pipe, as will be more fully set forth hereinafter.

The accompanying drawing represents a vertical central section of my invention.

A represents a cylindrical case, which is provided at its upper end with the exterior screw-threads, A, and which is 'interiorly screw-threaded at'its lower end, as at A, thus enabling it to be securedto the meter at its lower end and to have the service-pipe screwed to it at its upper end.

B represents a valve-seat, which has the rounded corners B, to admit of the ready escape of the gas, and the vents B, through which moisture that may collect in the case above the valve-seat may be discharged.

(No model.)

0 represents a plate located a suitable distance above the valve D. This plate 0 is pro vided with the openings 0, through which the gas can pass, andwith a central opening. 0, through which protrudes the stem D of the valve D. This valve is normally pressed against the upper side of the valve-seat B by means of the coiled spring E, with which itis provided. The tension of the spring is such as to only allow sufficient gas to escape from the meter to be consumed by the burners in the house to which it is to be attached, this being regulated to suit the varying sizes of the regulator that may be made.

A gas-regulator thus constructed is exceedingly simple, cheap, and serviceable, is positive and direct in its action, and is not liable to get out of order.

Having thus described my invention, clain1 The combination of the casing A, valve-seat B, having the rounded corners B and vents B, plates 0, provided with perforations, valve D, provided with a stem, D, which extends through the plate 0, and spring E, all combined and arranged to operate substantially in the manner described.

In testimony whereof I affix my signature in presence of two witnesses.

PETER KELLER.
